It is very easy to remember because it is a subdomain of the NASA web site. All I have to remember is the acronym for James Webb Space Telescope, JWST.
I had a look a look at the blog, I didn't realise it is so hard to cool down the sensor instrument to minus 266°c or 7 Kelvin. The cooler in there was working continuously for weeks to cool the system down. It sees in Infrared so it needs to be cold to see the stars. They mentioned that they want to look at the stars in hard to see places first, places that are behind dust clouds; infrared light is better at passing through dust than visible light.
It's not ready yet though.
